box. You should get something like this:
Change the Shutdown Option to Shutdown so it doesn't reboot on you. Once it shuts down, it is ready to move. When you boot it up in the new hardware, Vista will act like it has just been started up in your computer for the first time. Once you are booted you will have to install the drivers for your new hardware.
